C. B. NORTHRUP, OF NEW YORK, N. Y.

IMPROVEMENT IN SPRING BOOKING-HORSES.

Speci ation forming part of Letters Patent No. 42,960, dated May 31, i864 antedated May 30, 1864.

To all whom it may concern:

Be it known that I, C. B. NORTHRUP, ot' the city, county, and State ot New York, have invented a new and useful Improvement in Spring RockingHorses .and l do hereby de- 'clare that the following is a full, clear, and exact description of the same, reference bein ghad to the accompanying drawing, making a part of this specification, said drawing being a side view of my invention, partly in section.

This invention consists in applying a spiral spring to the horse and framing thereof', in such a manner that an agreeable rocking motion will be produced by a moderate effort of the rider, and at the same time a more durable and economical article obtained than those hitherto constructed, and are not attended with any danger to the rider in case ot the breakage ofthe parts.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents the horse, the rear legs, a, of which are secured to a rock-shaft, B, itted in ille back part of a framing, C, which supports ihe horse. This rock-shaft has a bar, b, projeeting a short distance from its back, and bearing upon a spring, D, of indialrubber or other suitable material, attached to a crossbar, c, of the framing G.

The spiral spring Gr may be constructed of steel, iron, or composition, and may be of conical,bieonical or cylindrical form. 'Ihis spring has atendency to keep the front part of the horse elevated, and when the rider is on the horse a very slight effort is required on the part of the former to give arocking or vibrating movement to the latter. The spring D serves as a check to the upward movement of the horse, and at the same time serves to give an impetus to its downward movement. The rock-shaft E admits of the rod F working freely in the hole d in the horse, and in case of the breaking of the spring the rod F will hold the horse or prevent its falling, so that the rider is in no danger of being injured.

The coil and flat springs, which are used with spring rocking-horses hitherto constructed,a1 e quite liable to break or become set,7 in consequence of the diiiiculty ot' properly tempering them, and in ease of breakage the horse falls and the rider is inrlanger of beinginjured.

My invention may be constructed at a less cost than those now in use, is more simple, and easily repaired ii' injured or deranged by use.

Having thus described my invention, whatI I claim as new, and desire to secure by Letters Patent, is-

The spiral spring G,titted on a r. d, F, which is attached to a rock-shaft, E, in the framing C, the rod F working in a hole, d, in the horse, and said parts being used with or without the checkspring D, substantially as and for the purpose herein setforth.

G. B. NORTHRUP.
